DETAILED DESCRIPTION

Reference will now be made in detail to the exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure.

Referring to FIGS. 1-6, a connection part 100 of an extendable patch panel 10 is shown. In one aspect, the connection part 100 defines a first side 102, an opposite second side 104, a top end 106, and a bottom end 108. The connection part 100 can also be defined as having a front end 103 and a back end 105. However, it is to be understood that terms such as “top”, “bottom”, “front”, and “back” are simply used to provide a relative point of reference for the various features of the connection part 100 and are not intended to require a particular orientation of the connection part 100.

The connection part 100 can be formed from a base portion 110 and an adjoining frame portion 112 extending between the first and second sides 102, 104. The connection part 100 can be configured such that the frame portion 112 is disposed generally orthogonal to the base portion 110, wherein the base portion 110 defines the bottom end 108 of the connection part 100 and the frame portion 112 defines the top end 106 of the connection part 100. The frame portion 112 can be provided with an aperture 114 for holding a plurality of telecommunications components 12, such as fiber optic adapters (see FIGS. 11-15).

In one aspect, one or more retaining protrusions 115 are provided extending from a side of the frame portion 112 and into the aperture 114. The retaining protrusions 115 allow for a telecommunications component 12 to be held in an upper part of the aperture 114 which can facilitate operator access to a lower component 12 by allowing for the selective increasing of space between any two components 12. As configured, the protrusions 115 are provided with a rounded shape and deflect outward with the frame portion 112 as a component 12 is being moved past the protrusion 115. Once a component 12 is moved above the protrusion 115, the protrusion 115 retains the component 12 from below such that the component will not simply slide back in a downward direction. As shown, two retaining protrusions 115 are provided in a frame configured to hold four components 12 below the lowermost protrusion 115. As such, the spacing between the top two components 12 can be increased by raising the upper two components 12 past the first or second protrusion 115. The frame portion 112 can also be provided with a third retaining protrusion 115 if it is desired to retain the second to bottom component 12 in a raised position wherein the spacing is increased between the second to bottom component 12 and the bottom component 12. Likewise, the frame portion aperture 114 can be configured to store any number of desired components 12.

The connection part 100 can be provided with various features that enhance the overall strength of the connection part 100 and the joint between the base and frame portions 110, 112. For example, the connection part 100 can be provided with a first sidewall 116 adjoining the first side 102 of the connection part 100 at the base and frame portions 110, 112. Similarly, the connection part 100 can be provided with a second sidewall 118 adjoining the second side 104 of the connection part 100 at the base and frame portions 110, 112. The connection part 100 may also be provided with support ribs 120 a to 120 f extending between the base portion 110 and the frame portion 112. The sidewalls 116, 118 and the ribs 120 a to 120 f significantly increase the structural integrity of the connection part 100 which is advantageous as adapters 12

In one aspect, the connection part 100 can be provided with one or more connection features to enable the connection parts 100 to be connected together in a side-by-side formation to form the extendable patch panel 10. As such, the number of interconnected connection parts 100 can be selected to obtain the desired size and length of the patch panel 10.

In one example, a first connection feature 122 can be provided on the first or second side 102, 104 of the connection part 100 and a cooperating second connection feature 124 can be provided on the other of the first and second sides 102, 104. As constructed, the first connection feature 122 of one connection part 100 a slidably engages with the second connection feature 124 of an adjacent connection part 100 b. Such a configuration is shown at FIG. 9 where two connection parts 100 a,100 b are joined. Any number of connection parts 100 can be joined together. The first and second connection features 122, 124 are configured such that they constrain the adjacent and interlocked connection parts 100 a,b from moving in a lateral direction (i.e. in a direction towards or away from the first and second sides 102, 104 and parallel to an axis X) and from moving forward or backward (i.e. in a direction towards or away from the front and back ends 103, 105 and parallel to an axis Y), but are allowed to slide up and down (i.e. in a direction towards or away from the top and bottom ends 106, 108 and parallel to an axis Z).

As shown, the first connection feature 122 includes a connection portion 122 a proximate the top end 106 of the connection part. Directly across from the connection portion 122 a, the second connection feature 124 is shown as including a connection portion 124 a. As shown, the connection portions 122 a, 124 a lie along the same axis (e.g. an axis parallel to axis X) such that, when joined, the connection parts 100 a,b are in a side-by-side arrangement with the front and back ends 103, 105 aligned along a common axis (e.g. an axis parallel to axis X). The first connection feature 122 may also include a connection portion 122 b that is similar in construction to connection portion 122 a and may also include a connection portion 124 b that is similar in construction to connection portion 124 a. As shown, the connection portions 122 b, 124 b are proximate the base portion 110 at the bottom end 108. In one aspect, the connection portions on each side 102, 104 of the connection part 100 are coaxially aligned such that connection portions 122 a, 122 b share a common axis parallel to axis Z and connection portions 124 a, 124 b share a common axis parallel to axis Z.

In one aspect, the connection portions 122 a, 122 b are each formed as a male tail structure and the connection portions 124 a, 126 a are each formed as an open ended female socket structure such that the connection portions 122 a, 124 a can slide onto the connection portions 122 a, 122 b to form a dovetail joint. It should be understood that a wide variety of interlocking shapes can be used for the connection portions 122 a, 124 a, provided that the shapes allow for sliding engagement.

To aid in initial alignment of the connection portions 122 a, 122 b with connection portions 124 a, 124 b, an alignment structure 122 c may be provided on the first side 102 of the connection part 100 while additional alignment structures 124 c, 124 d may be provided on the second side 104 of the connection part. As configured, the alignment structure 122 c extends fully between the connection portions 122 a, 122 b and is disposed between the alignment structures 124 c, 124 d which extend partially between the connection portions 124 a, 124 b. In one aspect, the alignment structures 122 c, 124 c, 124 d are formed as elongate members or ribs. Other shapes and arrangements of alignment structures are possible without departing from the concepts presented herein, provided that they allow adjoining connection parts 100 to be brought into initial alignment with each other such that the connection portions 122 a, 122 b can be interlocked to connection portions 124 a, 124 b by sliding one connection part 100 a with respect to another connection part 100 b along an axis parallel to the axis Z. In one aspect, the alignment structures 122 c, 124 c, 124 d are configured such that they can engage with each other by moving the connection parts 100 a,b towards each other in a lateral direction parallel to the axis X.

With the above described configuration, one connection part 100 a can be aligned adjacent to another connection part 100 b with the connection portions 122 a, 122 b of one connection part 100 a above or below the connection portions 124 a, 124 b of the adjacent connection part 100 b. As stated previously, proper alignment of the connecting parts 100 a,b is ensured by the prior engagement of the alignment structures 122 c, 124 c, 124 d. Once alignment is obtained, the upper connection part 100 a can be displaced in a downward direction parallel to the axis Z until the connection portion 122 a slides into the connection portion 124 a and the connection portion 122 b slides into the connection portion 126 b to lock the connection parts 100 a,b together at two distinct locations proximate the back end 105. This assembly process can be repeated until the desired number of connection parts 100 have been assembled together to form the extendable patch panel 10.

Each connection part 100 may be additionally provided with a third connection feature 126 and a fourth connection feature 128 to provide for an additional point of securement between adjoining connection parts 100 proximate the front end 103. As shown, the third connection feature 126 includes a connection portion 126 a that is provided on the base portion 110 proximate the front end 103. Similarly, the fourth connection feature 128 includes a connection portion 128 a provided on the base portion 110 directly across from the third connection feature 126. As shown, the connection portions 126 a, 128 a lie along the same axis (e.g. an axis parallel to axis X) such that, when joined, the connection parts 100 are in a side-by-side arrangement with the front and back ends 103, 105 aligned along a common axis (e.g. an axis parallel to axis X).

In one aspect, the connection portion 126 a is formed as a male tail structure and the connection portion 128 a is formed as an open ended female socket structure into which the connection portion 126 a can slide to form a dovetail joint, in the same manner as already described for connection portions 122 a/124 a and 122 b/124 b. It should be understood that a wide variety of interlocking shapes can be used for the connection portions 126 a, 128 a, provided that the shapes allow for sliding engagement. In combination, the connection portions 122 a/124 a, 122 b/124 b, and 126 a/128 a provide for three points of contact or securement between adjacent connection parts 100.

Each connection part 100 can also be provided with a first lock feature 130 and a second lock feature 140 to prevent adjacent connection parts 100 from sliding out of engagement with each other in either direction along an axis parallel to axis Z once joined. In the example embodiment shown, the first lock feature 130 includes a first spring clip 132 and a first stop surface 134 at the connection part first side 102. The spring clip 132 is provided with a free end 132 a that is disposed above a notched area 136 of the base portion 110. Similarly, the second lock feature 140 includes a second spring clip 142 and a second stop surface 144 at the connection part second side 104, wherein the second spring clip 142 is provided with a free end 142 a that is disposed above a notched area 146 of the base portion 110.

The first stop surface 134 is provided with a sufficient length such that the stop surface 134 of one connection part 100 extends into the notch area 146 and below the free end 144 a of an adjacent connection part 100. Likewise, the second stop surface 144 is provided with a sufficient length such that the stop surface 144 of one connection part 100 extends into the notch area 136 and below the free end 132 a of an adjacent connection part 100. Thus, an interference condition exists between the spring clips 132, 142 and the respective stop surface 134, 144.

As stated previously, two connection parts 100 a,b can be initially aligned with each other such that the second side 104 of a first connection part 100 a is adjacent to the first side 102 of a second connection part 100 b. In such an example, the first connection part 100 a can be initially disposed above the second connection part 100 b and then slid downwardly along an axis parallel to axis Z such that the connection portions 122 a/124 a, 122 b/124 b, and 126 a/128 a become engaged. As the connection parts 100 become fully aligned (e.g. the top ends 106 or bottom ends 108 are aligned), the second stop surface 144 of the first connection part 100 a will initially engage with the first spring clip 132 of the second connection part 100 b from above and force the spring clip free end 132 a to deflect inwardly. As the first connection part 100 a is further displaced downwardly, the spring clip free end 132 a of the second connection part 100 b will spring back or snap over the second stop surface 144 of the first stop surface 134 to prevent the first connection part 100 a from subsequently being lifted back out of position in a direction towards the top end 106. At the same time or near the same time, the free end 142 a of the second spring clip 142 of the first connection part 100 a comes into downward contact with the first stop surface 134 of the second connection part 100 b to prevent the first connection part 100 a from being further displaced downwardly with respect to the second connection part 100 b. Thus, the spring clips 132,142 and stop surfaces 134,144, once engaged, entirely prevent the connection part 100 a from moving upwardly and downwardly along an axis parallel to the Z axis, thereby ensuring that the connection portions 122 a/124 a, 122 b/124 b, and 126 a/128 a cannot become disengaged. If it is desired to disengage the first connection part 100 a from the second connection part 100 b, the spring clip free end 132 a can be manually deflected inwardly beyond the reach of the stop surface 144 whereby the first connection part 100 a can then be lifted upwardly and out of engagement with the second connection part 100 b. Alternatively, the second spring clip 142 can be deflected inwardly beyond the reach of the stop surface 134 to allow the first connection part 100 a to be displaced downwardly and out of engagement with the second connection part 100 b.

As shown in FIG. 9, the above described features result in an extendable patch panel 10 wherein each of the connection parts 100 are aligned together such that the front and back ends 103,105 are fully aligned along a common plane. However, where a staggered orientation is preferred, the relative positions of the connection features 122, 124, 126, 128 and the lock features 130, 140 on each side 102, 104 of the connection parts 100 can be offset on each side 102, 104 of the connection parts 100 to achieve such a result. It is also noted that each connection part 100 can be integrally molded or otherwise formed such that all features of the connection part 100 are formed as a single component.

A staggered configuration for an extendable patch panel 10 can also be achieved using a plurality of the above described connection parts 100 with the introduction of an intermediate adapter 150. The adapter 150 is shown at FIGS. 7-8 and a staggered configuration for a patch panel 10 is shown at FIGS. 9 and 12. To achieve this function, the adapter 150 replicates the connecting, aligning, and lock features of the first side 102 of the connection part 100 on a first side 152 of the adapter 150. Likewise, the adapter 150 replicates the connecting, aligning, and lock features of the second side 104 of the connection part 100 on a second side 154 of the adapter 150, but in an offset manner.

For example, the first side 152 of the adapter 150 can be provided with the first connection feature 122 including the connection portion 122 a, the connection portion 122 b, and the alignment feature 122 c. The first side 152 can also be provided with the third connection feature 126 including the third connection portion 126 a and can be further provided with the various components of the first lock feature 130.

The second side 154 of the adapter 150 can be provided with the second connection feature 124 including the connection portion 124 a, the connection portion 124 b, and the alignment features 124 c,d. The second side 154 can also be provided with the fourth connection feature 128 including the fourth connection portion 128 a. The second side 154 can be further provided with the various components of the second lock feature 140, presented in FIG. 8 as lock feature 160. As shown, lock feature 160 has a stop surface 162 that performs the same general function as first stop surface 144 and engages with the spring clip 132 of the connection part 100. Lock feature 160 can also be provided with another stop surface 164 that replaces the spring clip 142 and engages with the stop surface 134 of the connection part 100 to prevent further downward movement of the adapter 150 with respect to the connection part 100. As such, lock feature 160 of the adapter 150 interacts with lock feature 130 of the connection part to secure the adapter 150 to the connection part 100.

Referring to FIGS. 11-12, a fully assembled patch panel 10 having connection parts 100 a and 100 b joined together is shown. Although two joined connection parts 100 are shown, any number of desired connection parts 100 can be joined together. As shown, the connection parts 100 a and 100 b are aligned together such that the front and back ends 103,105 are fully aligned along a common plane. Each of the connection parts 100 a, 100 b are shown as holding a plurality of fiber optic adapters 12. Referring to FIG. 15, the fully assembled patch panel 10 is shown as being installed in a telecommunications enclosure 200 which may be configured to hold other telecommunications components 202. As will be appreciated by one having skill in the art, the telecommunications enclosure 200 shown in FIG. 15 may be provided with a cover (not shown) and cable seals (not shown) to form an enclosed housing. The base 20 can be configured with a mounting surface 22 to provide a support surface for mounting telecommunications components 202, such as telecommunications cables, connectivity equipment, splices, splitters, wave division multiplexers, and terminations.

Referring to FIGS. 13-14, a staggered arrangement of a fully assembled patch panel 10 is shown having connection parts 100 a and 100 b adjoining an adapter 150. Although two joined connection parts 100 and a single adapter 150 are shown, any number of desired connection parts 100 and adapters 150 can be joined together. As shown, the connection parts 100 a, 100 b are staggered such that the front and back ends 103,105 are not aligned along a common plane. Each of the connection parts 100 a, 100 b is shown as holding a plurality of fiber optic adapters 12.

Various modifications and alterations of this disclosure will become apparent to those skilled in the art without departing from the scope and spirit of this disclosure, and it should be understood that the scope of this disclosure is not to be unduly limited to the illustrative embodiments set forth herein.
